The PE ziplock bag can be sealed without the use of mechanical equipment. It will be sealed tightly with just one press. It can be sealed at will and is very convenient, hence the name.

The self-sealing bone of the PE ziplock bag is formed in one piece during film blowing. It is blown out through the film head of the film blowing machine, passes through the foam stabilizing frame to the herringbone frame, and is exported to the receiving frame through the traction roller. PE bone bags can be printed with copper plates or offset plates. The printing colors are generally 1-3 colors, and no more than 4 colors at most.
